What is the Cassandra connector for AWS Glue?

The Cassandra Glue Connector for AWS Glue simplifies the process of connecting AWS Glue jobs to extract data from Cassandra, and also load data into Cassandra. This connector provides comprehensive access to Cassandra data, facilitating cloud ETL processes for operational reporting, data governance, and more.

Connector options you need to set

• host (required) the Cassandra database host IP or domain that is publicly accessible.
• port (optional, default is 9042) the database port.
• keyspace (required) the keyspace (schema).
• datacenter (required) the datacenter (example: us-east-1).
• username (required) the database user's username.
• password (required) the database user's password.
• table (required) the table name you want to pull data, consider the case sensitivity in the table name.

The recommended approach to setting the connector options

Use AWS Secrets Manager can be used to store username, password and other sensitive information related to source connection.

The IAM Role you will be using in the Glue Job should contain the following policies

AWS Glue Service - To run the job. Amazon EC2 Container Registry - To access AWS Container Registry. Secrets Manager (optional) - If you use AWS Secrets Manager for connection options.
